If a function is defined with a reference to a base class as a parameter, one can pass an object of a derived class to it as an argument. The chapter covers the principal ideas involved in using inheritance for native C++ classes and C++/CLI classes. It highlights all of the important ...

Virtual Function是成员函数,其行为在派生类中被覆盖。与非虚函数不同的是,即使没有关于类的实际类型的编译时信息,也会保留重写的行为。如果派生类使用指针或者对基类的引用进行处理,则对被覆盖的虚函数的调用将调用派生类中定义的行为。 代码语言:javascript ...
